That sounds like a bogus transaction accelerator that rebroadcasts transaction instead of "mining" it; the keyword is "sent to 10 nodes".
Nodes automatically do that and it's unnecessary whatever their reason is.

The problem is it's ineligible for the free legit one that I know that actually accelerates txs (viabtc) because it's 0.241 satoshi short from the minimum 10sat/B fee rate.

As of now the priority fee is 40Sat/B.
Next time, if you saw that the recommended fee in the slider is quite high, set your transaction to at least 10sat/B so you can accelerate it through viabtc accelerator.
